REFRIGERATOR Filed Sept. 16, 1930 k ATTORNEY Patented Feb. 2,1, 1933UNITED STATES RUDOLF SCHLENK, OF VIENNA, AUSTRIA BEFRIGERATOBApplication led September 16, 1930, Serial No. 482,322, and in AustriaSeptember 17, 1929.

This invention relates to anew and imturally united to the fixed lid.The lowering proved type of refrigerator and aims at the attainment of anumber of advantages over existing types by virtue of the peculiararrangement of the parts by which it is characterized. The refrigeratorin accordance with the invention has a'rigidly fixed lid, while the bodyor case proper is adapted to be lowered away from the lid. The icechamber or refrigerating machine is structurally united to the lid. Inthe lclosed condition the horizontal upper edge of the body or case' isin contact with the under surface of the lid, so that the cold air tendsof itself to remain in the pot-shaped-body and no special arrangementfor forming a tight joint between body and lid is necessary. Doors andlocks can be dispensed with, so that the costs of production are greatlydiminished. The refrigerator is opened by the lowering of thepot-shaped`body away from the lid, which arrangement implies a saving ofcooling material or energy, since the cooled air within the refrigeratorhas no tendency to escape from the pot-shaped body but is loweredtogether with the latter when the refrigerator 1 is opened. A

One form of the invention is shownby way of example in the accompanyingdrawing, in which Fig. 1 shows a refrigerator in accordance with theinvention, partly in longitudinal section and partly in elevation.

Fi 2 is a section taken on the line -II-II of Fig. 1 through thesupportingdevice for the contents of the refrigerator.

1 designates the vessel receiving the liquid to be evaporized, 2 thepump serving for rel movin and compressing the air vapor mix- 40 ture.rom the pump a. conduit leads to the condensation water collector (notshown).

. The vessel 1 contains the medium to .be evapof rized y(volatilesubstances such as oils, b en. zine, ether, methylalcohol, etc.). Fromthe vessel 1 a. conduit 3 leads to the pump 2 from which another conduitruns to the condensaf tion water collector. 13 is the immovable lid, and14 the receptacle body or case proper of the refrigerator, this bodybeing adapted to be lowered while the parts 1, -2, S'are strucandraising of the body 14 is effected with the help of a simplecounterweight arrangement consisting of a set of pulley-wheels 15 and acounterweight 16.

It is advantageous to attach'the ice cham-1 ber or refrigerating machineto the under side of the lid in such a manner that it occupies aposition in the upper part of the y cooling chamber when therefrigerator is closed. This arrangement leads to further economy, sincethe coldest air trickles down over the articles to be cooled, becomeswarmed, and then rises up the walling of the refrgerating chamber. Theinner surface of the walling is thus swept by the relatively warmestair, which limplies a reduction in the loss of cold.

'lheemployment of the above-mentioned simple counterweight systemconsisting of a pulley set 15 and a counterweight 16 presupposes thatthe goods to `be chilled are not carried by the body of therefrigerator. It is therefore advisable to load the goods to be chilledon special supporting devices 32 75 attached to the fixed lid.

It is further advisable to subdivide the supporting device into stagesor platforms 38, 39, and 40, and to provide openings 42 in the upperstages to facilitate the accomodation 30 of particularly hi h objects(for example long-necked bottles Moreover certain of the stages may besov constructed as to occupy only a portion of the cross-sectional areaof the interior of the refrigerator, as shown in the drawing in the caseof the stage 39.

The refrigerator described above and illustrated in the acompanyingdrawing represents only an example of a form of construction embodyingthe present invention. The refrigerator and its details are capable ofmodification within the scope of the disclosed invention.

I claim 1. In a refrigerator the'combination with a fixed'immovable lidand a receptacle adapt-- ed to be lowered away from the said lid, andmeans for cooling the interior of the said receptacle, which means isattached to the said 100 lid and so located as to occupy a position inthe interior of the said receptacle when closed against the said lid.

2. In a refrigerator the combination with 5 a fixed immovable lid and areceptacle adapted to be lowered away from the said lid, platformsdisposed at varying distances from the said lid and adapted to beenclosed Within the said receptacle, means for the attachment of thesaid platforms to the said lid, and openings in those of the saidplatforms which are nearest to the said lid.

In testimony whereof I aix my signature.
